Structural Design Of Rcc Sloped Roof

Dear sir i wish to know how to design a rcc roof slab having a slope of 1 3 and over laid with roof tiles.

Structural design of rcc sloped roof.

Nov 9 2019 reinforced concrete sloped roof slab overhang detail cross section detail of a reinforced concrete sloped inclined roof slab overhang cantilever detail. Folded plate design structurally these roofs are folded plates so they require an engineer ing design. Different boundary conditions are considered like pyramidal panels a with and without ridge beam b with and without edge beam c supported on wall and d supported on columns with. Based on the boundary condition you can determine the axial thrust and the bending moment.

The roof should have a slope of at least 3 on 12 with a practical maximum of 6 on 12. Structural engineer sharjah uae. So i ve made three models in staad to study about the behavior of the building for different slope angles. Rcc slab laying is one of major step in any type of construction so it is mandatory to know all the points related to laying rcc slab.

This permits concrete place ment without the use of top forms. Here is a detailed article with all the information regarding procedure of rcc slab roof laying. If the problem is statically determinate the equilibrium equations would. Please do let me know how to cater for the horizontal force that the roof slab is going to give to the roof beams.

But bermudez says the design is relatively simple to create using finite element software. Model 1 has a slope of 36 degree model 2 has a slope of 26 degree. The primary aim of the work is to analyze and design the pyramidal roof slab. They have asked me to suggest the pitch height such that it is economical and also safe in design.

Sloping slabs under gravity load would be subjected to bending and axial thrust. Along the slope ii across the slope depending upon the boundary conditions.
